Why it works: Thyme and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Sir Henry Thompson’s Fish Soup
Ingredients
Directions
Make the stock
Melt the butter in a stewpan over low heat.
Add the sliced carrots, onion, shallot, cloves, thyme, and parsley, then fry gently until they turn reddish.
Pour in the cold water and bring to a boil, skimming occasionally.
Add the haddock pieces and the head and bones of the whitings, and season with salt and pepper.
Simmer gently for 2 hours.
Remove the bones and strain the soup through a coarse strainer.
Finish and serve
Divide the whiting fillets into small portions and boil them in some of the stock for a few minutes.
Garnish with chopped parsley and chervil.
Serve in a tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Builds a rich fat base in which the vegetables soften and take on colour.
- Carrots
- Add sweetness and body to the stock as they cook down.
- Haddock
- Releases flavour and gelatin into the stock during the long simmer, giving depth.
- Whiting fillets
- Provide tender pieces of delicate fish that cook quickly in the hot stock.
The step that matters
Skimming the stock as it comes to a boil. Skimming removes coagulated proteins and impurities that would otherwise cloud the soup and taste bitter or scummy, leaving a clearer, cleaner broth.
Swap the onion
How well each one fits the dish's main ingredients (butter, carrot, shallot, clove, thyme, parsley, haddock):

Fit is the average pairing score against butter, carrot, shallot, clove, thyme, parsley, haddock. Candidates are from the same food group and used in at least 100 recipes.
